What makes a religion?

[Mystic]

That's a linguistic idiom...and isn't going to be suitable as the contents of a logical proposition.  For flavor, here is ours.

Religion - obligation, bond, reverence

Seems meaningless without context eh?  So does "what we follow" in english.

I follow the car in front of me.  Is that my religion..by either little idiom.....?  OFC not.

This is not how language work. Words all of a different context. I said follow, but the word is more closer to "obey". But then you might say obeying my boss is a religion, etc, but it's obviously not referring to that.

The root word just shows it has to do with what we decide to obey and follow in life, and the word "worship" comes from the root to be enslaved to, and the word ilah (god) comes from the word to what diverts us from things towards that. 

So you combine them, and you get over all image. However, the root words, often give an idea, but they are not the meaning of the words themselves.
